In the configuration of Figure 11 shown type, single fiber may be only had in cable 70 He in connector 34.Therefore, may expect to use Wave division multiplexing technology to support the two-way communication on optical fiber.Wave division multiplexing can utilize Wave division multiplexing (WDM) optical fiber to realize.As shown in figure 12, such as, corresponding WDM filter can be coupled to every one end in path 16.In the device 12, source 212 can by optical path 290(such as, optical fiber) be coupled to the input port of WDM filter 288.Detector 218 can by optical path 292(such as, optical fiber) be coupled to the output port of WDM filter 288.Path 200(such as, optical fiber) (by directly to connect or through optical path expansion, the optical path expansion 206 of such as Fig. 2) the input-output port of WDM filter 288 can be coupled to.In equipment 14, WDM filter 294 can have input-output port, (such as, by optical path 296) of being coupled to path 200 and be coupled to the input port that the output port of detector 250 and (such as, by optical path 298) are coupled to source 246.
